General background We are a little slow getting off the mark with our updates this year.  The UC ANR web platform was changed in the last month and we're having some issues migrating the old website and blogs over to the new platform.  In the meantime we're using this web hosting platform. 

Thrips development: The first post winter generation adults peaked around the end of March.  Peak egg hatch for generation 2 probably peaked a couple of days ago (4/19). Generation 2 adults will peak in the first week of May.  Unless there is evidence of TSWV attacking crops this early, it is unlikely that treatment for thrips will be useful at this time. 

Model outputs: While we're working to get the new UC ANR webpages ready we've made a simple alternative place to view the phenology model output for your region. You can see the model at the link below. Note that this is hosted on a third party web server, Neocities.
